ci: Regenerate with latest 'lcitool' and fix manual job definitions

The latest lcitool merged the 'prebuilt-env' and 'local-env' jobs into
one which use variables to pick up the right environment and steps
rather than duplicating everything.

Regenerate the generated job definitions, fix the helper definitions
and also fix the manually defined jobs (website-job).
